    摘要： The present invention relates to a method for preparing an artificial patination material to substrates, preferably made from copper or copper alloys and a patination material. The raw material is a copper salt, which reacts with an alkali metal hydroxide. The precipitate is dispersed with powerful mixing and an addition of a dispersing agent. An oxidative agent like manganese dioxide is used, and carbon is used as an agent for catalysing natural patina forming. Metal compounds are used to achieving desired colour and/or colour tinge. The invention relates also to the corresponding patination material.

    摘要： The invention relates to an apparatus for rolling a metallic product comprising a mill frame (18), a first cantilever roll shaft (19), a second cantilever roll shaft (20), both said roll shafts (19, 20) being mounted on the mill frame (18) with two sets of bearing assemblies (38, 39, 40, 41), a first roll-ing ring (21) mounted on the first roll shaft (19), a second rolling ring (22) mounted on the second roll shaft (20) said rolling rings (21, 22) forming a nip (23) in between, at least one ring (29) arranged with its inside surface (43) in rolling contact with the first roll shaft (19) and with at least one intermediate roll (27), which intermediate roll (27) is ar-ranged also in rolling contact with the second roll shaft (20) and at least one drive end (42) arranged at the end of either roll shafts (19, 20) for driving the mill (16). The in-vention also relates to a method of producing a metallic product.

    摘要： The invention relates to a method of manufacturing heat transfer tubes for a heat exchanger such as an automobile radiator. The tubes are preferably formed of copper or a copper alloy. A sheet of the material is folded into a shape that resembles a B and is brazed together with a brazing material that is free from flux. The brazing material is in the form of a foil or paste. The paste typically includes a powder filler, a binder, and a carrier, which may be a liquid or a wax.

    摘要： The invention relates to a method for producing a metal tube (1), comprising arranging one or more metal profiles (3,5) to form at least one channel (7a-c) for conduction of a fluid, feeding the one or more metal profiles (3,5) into a clad-rolling mill, and clad- rolling at least a first (9) and a second portion (11) of the one or more metal profiles (3,5) to each other, so that the first and the second portions (9,11) are joined with each other, wherein the first and the second portions (9,11) form a seal (13) that holds the one or more metal profiles (3,5) together and seals at least part of the channel. The invention also relates to a clad-rolling mill adapted to produce a metal tube and a metal tube (1).
